Inventor: KIM GEUN U
IPC: H04L12/28
Filed: 2002-07-26
Abstract: PURPOSE: An RREQ(Route REQuest) message using a PF(Participation Flag) in an AD-HOC network and a method for setting up routes are provided to selectively carry out route setup according to the residual power of each node by adding and inserting a PF into an on-demand routing protocol RREQ message. CONSTITUTION: A source node in an AD-HOC network adds a PF, of which the flag value is the first value, to an RREQ message and transmits it to each peripheral node(S10). Then the source node judges whether RREP(Route REPly) messages are received from the peripheral nodes within a preset time(S20). In case that RREP messages are received within the preset time, the source node sets up the first route, which is normal, with the nodes of which the residual power is more than a preset reference value(S30). However, if RREP messages are not received within the preset time, the source node judges that it is impossible to set up a route using nodes having sufficient residual power. Accordingly, the source node retransmits an RREQ message, to which a PF having the second value is added, to each peripheral node(S40). Then the source node judges whether RREP messages are received within a preset time(S50). In case that RREP messages are received, the source sets up the second route, which is urgent, using the nodes of which the residual power is less than a preset reference value(S60).
